Impending failure of monumental proportions. Being told this phrase can only mean one thing: there is absolutely zero chance of any victory. There is only complete and utter conquest and slaughter. The prase most suited to noobs with a poor grasp of the reality of the situation
In Star Craft:
Me: You should really build your defenses up.
noob: <doesn't build defenses up>
Me: Epic fail imminent...
noob: <suffers epic death>
